Brewpi Spark Firmware 0.2.6 Released

Can you try forcing recalibration by entering this on the command line?

echo -ne 'T\n' > /dev/ttyACM0

It just sends a T over serial, but that will start the calibration routine on the device.

I suspect there is a bug in storing and loading the touch screen calibration.
The settings are stored and restored in this file:

Can anyone spot a bug?

That worked. It launched the calibration screen, and now it registers touches in the correct areas. Thanks!
